中文摘要：

综合采用GPS、磁悬浮陀螺全站仪、水准仪以及全站仪等仪器设备,进行高精度矿山三维控制网建立.以某矿区现场实践为例,系统介绍建立井下7＂级导线及四等水准控制网的主要步骤及其主要技术指标,包括：地表E级GPS网的建立、井下7＂级导线测量、四等水准测量和陀螺定向,以期为类似矿区控制网的建立,提供有效的理论和实践依据.

英文摘要：

To establish three - dimensional control networks of coal mine accurately, an approach to employ different instruments was proposed, which included GPS, magnetic gyro, leveling, tatal sta- tion, etc. A coal mine was taken as an example to prove the practicability of the approach, and the main steps and technical specifications for the implementation of the fourth - grade leveling and 7＂ traverse underground networks were given simultaneously. The principal works include the networks establishment with E - grade GPS overground, and 7＂ traverse and the fourth - grade leveling under- ground, and gyro -orientation, for providing a theoretical basis for networks establishment under- ground and giving a reference to other similar coal mine.
